Maxim Efremov,


The interaction of particles or macroscopic bodies is a key element of Nature for building up nuclei, atoms, molecules, gaseous, liquid or solid states of matter, and even the system of planets with galaxies. Determined by physical conditions such as dimensionality, environment, and type of particles, their direct and indirect interactions can have short-range (nuclear and the van der Waals forces) and long-range (the Coulomb potential in atoms and molecules or the Newton potential in solar system, and dipole-dipole interaction) characters.
The seminar will review recent and promising activities in exploring different physical systems consisting of a few particles. Special attention is paid on finding and observing new effects, induced entirely by a small number (three, four, or five) of interacting particles. In particular, for the discussion sessions, we envision the following research topics:
Theoretical tools to study few-body systems
Few-body states induced by resonant forces in mass-imbalanced systems
Three- and four-body forces in systems with effective degrees of freedom: few-nucleon systems, halo nuclei, and helium clusters
Systems of charged and neutral atoms: ions and neutral atoms, Rydberg molecules
Few-body systems with long-range and high-asymmetric interaction: double ionization process, dipole-dipole interaction
For each of these topics we have been able to attract lecturers, who have made pioneering and outstanding contributions to the field on an experimental and theoretical level.
